- JWST has taken a DIRECT spectrum of an exoplanet mass object (it could be a failed star, the jury is still out on that one) and it is the most detailed, beautiful spectrum you ever did see. It's revealed the existence of silicates (think sand) in the atmosphere and suggests it has very dusty clouds and storms. It's also orbiting around TWO stars, so there's been a lot of comparisons to Tatooine from Star Wars! #jwst #astronomy #astrophysics

👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

Whoever this Collaborators person is, they help out a lot
Et al is my favorite researcher.
@@silverXnoise they're everywhere! Mad respect for all the knowledge Et al has
Little known fact, it's actually Dr Christine Ollaborators PhD.
imagine if they worked with others!
My personal ambition is to get a research job in Teralia. I keep hearing about amazing discoveries made be a couple of scientists in Teralia.
You can tell how passionate Becky is with her job and channel. I love it, keep it up!
I love that passion too. Oh I love the bloopers. Becky unplugged, awesome.
You can indeed. And now you’ve told it too. I think we can rest assured nobody’s missed it now.
i wish someone would look at me the same way she looks at JWST data
@@beepboop204 Stick a huge gold plated mirror on your face then!
I think the Rebecca Smethurst Space Telescope could launch itself into orbit.
Back in 1993, in the "Master Of Orion" game there was a technology named "Advanced Space Scanner" that reveals the properties of distant planets. At that time it was pure fiction, not even scientific, and I didn't expected I would see similar technology in real life!
The spectrum of an exoplanet's (or failed star) atmosphere, with traces of silicates and stuff... Amazing, simply amazing!
I'm playing MoO2 right now.
Yeah the Master of Orion games are available on Steam
I was going to say the same thing! I played that game quite a bit, and had the same thoughts about the space telescope tech. Maybe we need to switch some resources to terraforming our own home planet.
Good old MOO played II and III a lot.
Stellar spectrography has been going on since the 1850s. Researchers actually predicted the existence of helium from observing the spectra of the sun back in the 1860s, 30 years before it was discovered on Earth.
Astronomy has never been so exciting, or presented with so much enthusiasm. This has brightened what has been a difficult anniversary for me personally. Thank you Dr Becky.
We've gone really far from the discovery of the first exoplanets in the 90s to a full spectrum of an exoplanet!
Humans are amazing.
That's what I was thinking too. :)
There was a time a few years after the first 2, where could keep track of the names or some details of the discoveries. Things have escalated so quickly in the last ~15 years to the point where we went past 5000 a few months ago oO
We're basically reaching science fiction levels of this.
@@vigilantcosmicpenguin8721 Because thats exactly what this is ..... fiction.
I really do love how animated you get when you are excited (passionate?!) about what's going on. Please never lose your spark Doc.
I had the pleasure of hosting Dr Beth Biller (2nd author on the Miles et al paper) for a seminar on this research the day the press release went out.
Really exciting research! I work on higher-resolution ground-based spectroscopy, but I'm a little jealous of the lucky people who work with the Webb data!
I’m quite jealous of the work you get to do. That sounds super interesting.
I would love to do this work but my maths skills are not even close to good enough.
Can you tell me about the ground based spectroscopy? I sell mass spectrometry instruments, curious of yours
Dr. Becky is my favorite nerd. Her enthusiasm for astrophysics tickles my soul. I only wish I could understand half of the math involved with what she is saying. I love astronomy. ❤
This is definitely squee-inducing use of the JWST. Kudos to you, Dr. Becky; I really appreciate what you are doing to present the materials you are reviewing in your videos. You are amazing; please continue providing astronomy data!
It is genuinely heartwarming to see how excited Dr. Becky gets.
I love that we're examining planets and whatnot but I thought we'd moved on from storing data on video tapes 👀
Edit: and the instant I make that joke I get to the part where Becky kills me and turns the knife on my joke.
I was still juggling the words for a betamax joke around...
You gotta use technology you have. For example when we moved from films to CCD cameras it was sudden jump in detection. Films have quantum efficiency (how much photons they detect) of 1% or maybe 2% while worse CCD cameras have quantum efficiency of 40%. Now better CCD cameras have efficiency of about 90%
If you think this VHS update rocks, wait till you see the BetaMax one!
@@hugegamer5988 There's a special Nipkow disc version available.
@@realdragon The were talking about the name of this system: VHS, which has nothing to do with VHS tapes, but with the name of the instrument they were first observed with.
Another good presentation on recent findings and how much the JWST data is adding to our understanding of space around us. I would like to make one minor suggestion - not every time, but occasionally go into a little more detail on those spectrograph charts and how the certain lines and spikes show specific molecules. Sometimes I've seen graphs that look rather obvious, but occasionally the various emission lines are not as obvious to other than trained researchers. Great job on your explanations.
Yeah, I really don’t need to see another Pink Floyd prism graphic (and only the low resolution instrument uses prisms). A bit of actual detail would be nice.
Yeah, I would really love to hear a brief explanation of how you can detect different isotopes in an emission spectrum. I didn't think that was possible. Great video, though; I love your enthusiasm!
@@andrewthomas7109 I would think that that requires hyperfine splitting, which depends on the spin of the isotope, but it's tiny...maybe if the emitter is in a strong magnetic field you get some Zeeman effect? idk. edit: that Zeeman effect comment is non-sense. it happens.
@@andrewthomas7109 never mind. At 8:49, it's not atomic physics, it's molecular excitations, which are strongly dependent on the mass of the atoms participating in the excitation.
I LOVE your channel. I have recommended it to so many friends and family who have since told me that they love it as well!! Keep up the excitement and the great videos. Your enthusiasm and knowledge continue to blow me away. Love, love, love!
I love it when You Nerd out, while telling Us about it, Dr. Becky. It's fantastic.
I'm so happy I found the astronomy corner of the internet! There are few people irl who get excited about JWST news!
Hello dr Becky, thank you for your great work! I always enjoy watching your videos and I'm always amazed. All the best to you, your channel and your loved ones!
as a side note ... i love the end credits / bloopers! it definitely keeps me watching to the *very* end :)
YEAH, they're cool, but I only see them because I'm glued to the chair.
I absolutely love listening to you. Aside from the information - which fascinates me - and your enthusiasm for it, I have to admit to finding your voice adorable! More Dr. Becky is always a joy!
I love your enthusiasm compared to the existential dread you find in most space videos. I think I'll stick around.
Thanks for your video, You remind me of a certain math teacher.
So our attempts at fusion are not attempts to model a star, but attempts to model a Brown Dwarf. You are a fountain of knowledge in your field. Completely fascinating. You are truly an intellectual Goddess.
Thank you Becky, this is facinating information. Looking forward to more.
This is so awesome! I have been lucky enough to look at the spectra of this exoplanet (and in particular the silicate absorption bands) in my undergraduate research and it is awesome! I am also super excited because we will be observing a brown dwarf with prominent silicate absorption (J0624) on Monday, April 3rd with JWST. Exciting stuff is going on in the astrophysics community
Sounds like fun times indeed. Out of curiosity, has it been difficult to scale up 'looking' at the data, when there seems to be soo much more of it than from before JWST data?
LOVE your vids so much Dr Becky. Thanks for all the top notch content
The whole gravitational interaction between those 3 objects is just so cool to think about. The "planet" is not that much "smaller" then the 2 stars it orbit. Amazing system.
Dr. Smethurst; again I thank you. I wanted to be an astrophysicist, but fairly early in my drive (my fifth semester in pursuit) I ran into a professor who was so cruel he crushed me and I ended up having to just be a hobbyist-astronomer. What I love most about your videos is that I can share them with my 10yo son and he can understand what you are saying. Thank you for your #ScienceCommunicator skills. I always look forward to your next video, so now I await the next.
JWST is just the gift that just keeps on giving ! I thought that we had our expectations set high with Hubble but we're not disappointed with the data that JWST is providing.......Hoping we get decades of use out of this.
your excitement is contagious, thank you.
I love your "oooooh", announcing the new discovery! And I love everything about your channel. Thanks for the knowledge.
Yet again, Webb is showing exactly how much it's worth to science! Thanks, Dr. Becky, for all you do. 😊
❤️❤️
@drbecky, I just finished your book. Thank you. For a subject that is so dense, you made it easy to digest. Also, I feel so smart reading on the metro.
Your excitement is contagious!
I used to be so excited when you made appearances on Sixty Symbols and Deep Sky Videos. So glad you have your own channel now! I cant get enough Dr Becky haha
You’ve got to love the enthusiasm Dr Becky has in her job😄.
I truly enjoyed the opening expression of joy+excitement.
It's amazing we live in an age where we can learn so much about planets so so far away from us.
As soon as I saw silicates I thought "hmm, possibly a rocky core, and DUST STORMS!". This is exciting stuff!
Right? That part shocked me. But it would be VERY hot and the gravity and potentially the atmospheric pressure would be absolutely insane.
Oi. Im just a cook, 29 years of age and still trying to get my bachelors. I love to learn and things like this help keep me excited to pursue my education. Thank you!
Dr. Becky.
Your happiness is contagious. 😁
Thank you!
Pretty interesting news indeed! Thanks, dr. Becky! 😃
Stay safe there with your family! 🖖😊
Bit drunk and bit high, still thinking that is so difficult to find real information out there, and some how you gain a spot in my subscriptions because of this.… just wanted to say really THANKS from 🧡my.
Regards from Colombia 🇨🇴!
i love the no intro/full info ahead format !
I happened to have the volume up as this video started. My ears are ringing.
She makes it incredibly fun & super clear to follow.
Inserting the Pop culture reference The Jeannie Aladdin was just Marvelous Darling. well done.
love your show Dr Becky.
Thanks for the video!
I just love the enthusiasm.. this is the true wonders of science. To experience that there is so much new knowledge to be extracted.. it just gleams from your eyes
The Paramore at the end caught me off guard! I knew there was a reason I trusted you Dr. Becky 😁
Thank you for sharing this.
That planet is way out there!
JWST is paying off really well.. and to think we're only scratching the surface.. :-)
Images out of reach !!
The best part of all your videos...THE BLOOPERS LOL. Another great video Doc. Thanks and keep 'em coming.
Thank you Dr Becky
Loved the entire video, but I had to stop, hit like and subscribe, when you threw in the Genie's 10,000 years line. **chef's kiss**
Thanks Becky. Exciting times, indeed! 🙂😉
Thank you Becky 🙏😘
Overall just a great bit of science news! And Dr Becky is charming! Thanks!
I caught that Paramore reference 😂❤ Love your videos!!
On the one hand we have sublimely detailed scientific data enabling us to answer complex question about the universe, delivered by a dedicated, passionate, and hard working PhD. On the other hand we have millions of people who think the moon landings were faked; and thousands who think the earth is flat and that all science is a government conspiracy. Sometimes I don’t know whether to laugh or cry.
Great stuff Dr Becky, tons of love from me, here in West Virginia. I hope we find life one day……..Oh, I love your enthusiasm. 0:42
Love how you get all giddy from excitement at the prospect of all that science JWST is promising to enable at the end… 😊
Glad you like silicates. I think they rock.
I now have your song stuck in my head.
Amazing; and we are just starting ❤
I love watching videos on my field, and hearing the names of people I've cited or my team has collaborated with!
I love that you think of Alladin when saying the words "ten thousand years!". I have always done the same thing, whenever I have cause to say 10,000 years my brain thinks of that quote lol.
When I saw this in the news I was excited to hear your assessment! No little green people but awesome news just the same 😀
Love the outtakes
The cheese definitely fell off your cracker at the end 🥰
Top crush 🥰🎉🎉😂🦊❤️🙏🏼
I was a physics major in college but I decided to switch to math for grad school, thanks for making these videos so I can stay in the loop!
Thanks. You are very good at explaining complex information to knucklehead like me.
Your enthusiasm is contagious
How detailed that spectrum was *really hit me*
Failed stars - the Steven Seagalls of the galaxy. Very sad - but also fair.
Awesome. Just a great time to be an astronomer.
I've never seen such a detailed spectrographic analysis of anything before.
You might try looking at a “detailed” spectrum of the Sun.
I think the best videos are the ones where the bloopers reel is longer than the outro 😂
It's nice that although demoted to dwarf planet, the Pluto still gets attention and a mention
That was dope 😎🤲💥
Singing paramore ❤ officially my favourite channel
Exciting.
Whenever the doctor gets excited it's usually a good morning! 🤣
that moment when it was mentioned it's further out than pluto "Ok wow but...wait 1 single orbit 10000 years...holy mother of ...". Space facts will never cease to amaze. NEVER! Even if humans manage to travel back to the beginning of the universe I bet there will still be even more answers and surprises
That is exciting.
Hey Becky, a long time ago I sent you an email as a worried aerospace engineering student anxious about changing to his true dream course, physics & astrophysics. I'm now going in the fourth year of astro, and although I might end up not even trying a phd (i need money so i'm gonna be a programmer, which is ok because i love that too), I want to thank you for your advice back then as it helped me decide on this life path which was definetly the right choice.
Wonderful to hear that I could help you on your path 🤗 all the best with the rest of your studies!
Good vid becks ,, fascinating stuff 🤔👍.
I love this. That telescope is gonna be busy with all the research requests
My personal definition for intelligence is the ability to make complex ideas simple to understand. Given that standard you are brilliant.
"It's 4 times further out than the PLUTO" 🤣. You're awesomeness Dr Becky!
Becky...I C I'm so proud? I Don't think people are aware however I am !!! Good job absolutely amazing Amazing!!!! I'm so happy 😊
I come here because of the science, but I stay for the singing in the bloopers! :)
great time for scientist thank you
I mean this is probably the most we will ever learn of these places at least in our lifetimes. What privilege to learn about all this!!
Yeah, the future of space exploration, even in our corner of the galaxy, is very much all about building the most capable telescopes with which to view stars and planets from afar. Telescopes in perpetually dark craters at the poles of the Moon need to happen at some point, followed by fleets of interferometer telescopes roaming the outer solar system away from all the dust and zodiacal light reflecting off it that will eventually limit observations in our vicinity.
The fact that JWST can see exoplanets at all blows my mind!
Yaaay for the Paramore at the end !
This is really a life changing discovery. I feel much better now…
☀️Merci.
Watched 1 minute. Instant subscribe.
You lost me at new exciting news, 😂, but the enthusiasm is exciting. Keep up the good work.
You do a great Mickey mouse !
Good to see sub's rising with the PBS Link
🧙♂️🥳
you dont even talk about the spectrum for one minute! i think its still a good and informative video, but i would like more details on the actual piece of science you are talking about. thanks for making the video
I wish I still had the enthusiasm for my profession that Dr. Becky has for astronomy.
